I have two voice recorders and they are excellent. Strangely, I prefer the oldest one. It is more usable than the newer VR. I also have a smart pen. It can record audio too. They are great when you are in a meeting. You can record the audio, while you take notes. You can then save the files (both audio and text) to your computer. They are a bit exy but great for students or if you need a record of a conversation or have to take minutes in a meeting.
I have had to do many, many interviews over the years and the VR was just essential.
I like the idea with the music. How often do you hear something and think, “I like that” but you don’t know who it is and then you can’t remember enough about it for someone to tell you. To hear your dad’s voice would be very special. It is sad how soon you forget the sound of their voices. That’s a real treasure. Hopefully, something we said will be useful to Zen!
